How Promptly's No-Code App Builder Works Step by Step

Updated

Promptly is a no-code platform for building generative AI apps, agents, and chatbots. You pick a template, attach your own data, and publish — no coding required. The three-step flow below applies whether you're building a customer-facing chatbot or an internal tool over your documents. You'll need a Promptly account to start; the site offers a free start option, while paid tiers and an Enterprise plan are referenced on its pricing page.

Step 1: Pick a template and configure it

Start from Promptly's template library rather than a blank canvas. Each template maps to a use case, so you skip the setup work of defining an app from scratch.

What you do:

  • Choose the template that matches your use case.
  • Provide the input and configuration the template asks for.
  • Decide how the output is rendered.

The output-rendering choice matters more than it looks: it determines whether users see a chat reply, a structured answer, or another format. Pick this before you wire in data, since it shapes what your data sources need to return.

Step 2: Add your data

This is where a generic chatbot becomes your app. Promptly connects your existing content to the underlying models so answers are grounded in your material rather than the model's general training.

Supported data sources include:

  • Files (PDFs, PPTs, audio)
  • Website URLs and sitemaps
  • YouTube links
  • Google Drive
  • Notion exports

You add these sources in the app builder and attach them to your app. In practice, the choice of source changes your prep work: a sitemap is the fastest way to cover a whole site, a PDF suits a single policy or manual, and a YouTube URL builds an app on existing video content without transcription work on your side.

Promptly also supports model chaining across major providers — OpenAI, Cohere, Stability AI, Hugging Face, and others — plus processors for higher-level functionality. If your use case needs more than one model in sequence, this is configured here rather than in code.

Step 3: Publish and access your app

Once your template and data are set, save and publish. You then reach the app three ways:

Access method Best for
Dedicated app page Sharing a ready-made link with users
Embed code Adding the app or chatbot to your existing website
API Running the app from your own applications

For embedded chatbots, you copy and paste a code snippet and can customize the look and feel — including a logo — to match your site. Promptly also supports building GPT-based Slack apps and Discord bots backed by your data, again without coding RAG pipelines.

What to check before you commit

  • Data readiness. The quality of your app tracks the quality of what you attach. A messy Notion export or an incomplete sitemap will surface in the answers.
  • Output format. Decide early whether you need a conversational widget, an embedded assistant, or an API endpoint — each implies different integration work downstream.
  • Scale and security. Promptly states the platform is built for scale and security and offers APIs for running apps and endpoints plus programmatic data upload and management. If you're deploying inside an enterprise, confirm the specifics of the Enterprise plan against your requirements before rolling out.

If your goal is a quick prototype, the template-plus-data path gets you to a published app in minutes. If your goal is production integration, plan the API and data-management side from the start rather than treating it as an afterthought.
